The catalogued J2000 position is carried along the great circle the object's own published motion puts it on, at a constant velocity, and the result is referred to the true equator and equinox of this instant. Those are separate things: the motion moves the object, and the rotation turns the grid under it by about fifty arcseconds a year, with nutation adding up to another seventeen.","excluded":"Parallax, the radial-velocity perspective term, aberration and refraction; each is below the accuracy of the catalogued positions themselves. An object with no published proper motion comes back where the catalogue has it rather than at a fabricated zero, and says so with a null pm_ra_mas_yr. A body with no fixed position is not propagated at all — its place comes from an ephemeris, which is what /api/v1/visible answers with."},"slug":"ic-1385","name":"IC 1385","class":"intermediate_spiral_galaxy_sabb","category":"galaxy","object_type":"Intermediate spiral galaxy SABb","mag":18.25,"mag_band":"V","abs_mag":null,"abs_mag_band":null,"distance_ly":730345672.0127258,"distance_method":"redshift (CMB frame), flat ΛCDM with H0 = 70 km/s/Mpc","ra_deg":322.21329166666663,"dec_deg":-1.070111111111111,"epoch_ra_deg":322.559118,"epoch_dec_deg":-0.953045,"epoch_moved_arcsec":null,"pm_ra_mas_yr":null,"pm_dec_mas_yr":null,"orbits":null,"semi_major_axis_km":null,"periapsis_km":null,"mass_kg":null,"mass_msun":null,"constellation":"Aquarius","discovered":null,"featured":false,"url":"https://spacecatalog.org/object/ic-1385","radius_km":null,"radius_kind":null,"data_quality":null,"description":null,"properties":{"b_mag":15.45,"h_mag":11.85,"j_mag":12.6,"k_mag":11.58,"v_mag":18.25,"redshift":0.05154,"hubble_type":"SABb","wikidata_id":"Q3710365","redshift_cmb":0.0503831384236606,"ngc_type_code":"G","uncertainties":{"distance_ly":[32804018.23021639,32804018.23021639]},"major_axis_arcmin":0.59,"minor_axis_arcmin":0.53,"position_angle_deg":141,"surface_brightness":22.99,"radial_velocity_km_s":15054},"designations":[{"catalog":"2MASX","designation":"2MASX J21285116-0104121"},{"catalog":"IC","designation":"IC 1385"},{"catalog":"IRAS","designation":"IRAS F21262-0117"},{"catalog":"LEDA","designation":"LEDA 66832"},{"catalog":"MCG","designation":"MCG +00-54-022"},{"catalog":"PGC","designation":"PGC 66832"},{"catalog":"SDSS","designation":"SDSS J212851.12-010412.4"},{"catalog":"SDSS","designation":"SDSS J212851.19-010412.4"},{"catalog":"SDSS","designation":"SDSS J212851.20-010412.4"}],"source":{"id":"openngc","name":"OpenNGC","url":"https://github.com/mattiaverga/OpenNGC","license":"CC-BY-SA-4.0"},"updated_at":"2026-09-02T19:50:56.720Z","attribution":"Data from SpaceCatalog.org.
